Application filed July 25, 1908. Serial No. 445,403.

To all ywhom 'it may concern:

Beit known that I, GEORGE KENT WED- LAKE, ofthe city of Brantford, inthe county of Brant, in the Province of Ontario, Canada, have inventedcertain new and useful Imroveinents in Traction-Flows, and ParticuarlyTraction Gang-Flows, of which the following isa specification.

Myinvention relates to improvements in traction plows.

One object of the invention is to so support the triangular frame orhitch of the plow as to keep it on a level with the ground andconsequently with the engine, so as to insure even running of the plow.

Another object of the invention is to devise a form of runnin f sup ortfor the plow frame or hitoh,whic wili) enable it to be drawn easil andwithout gathering stubble,

grass or ot er obstructing material, which would impede its progress.

Another object of the invention is to devise .such a form of running suport for the plow frame or hitch as to ena le it to be turned readily.

A further object of the invention is to imi provey .the construction ofthe plow dra@ eams so that they may be readily connected to the `frameor hitch and adjustedto roper drawing position, that is-parallel to t eline of draft, and in oblique alinemcnt with each other.

A still further Object ofthe invention is to improve the construction ofthe plow drag beams and their connections to the frame or hitch, so thatwhen connected and adjusted the plow drag beams may be held rigidlaterall y though moving freely up or down.

To effect theirst mentioned object I have constructed my traction gangplow with leading supportin wheels, an intermediate Supd porting whe-ejournaled in the rear of and near the narrow forward end of thetriangular frame or hitch and a rear supporting wheel journaled inproximity to the rear apex ofthe triangular frame or hitch.

To effect the second mentioned object I have made all the supports ofthe plow frame or hitch, wheels or running su ports.

To effect the third mentione object I have made theA leading wheels orrunning supports of the plow frame or hitch, caster wheels.

To effect the fourth and fifth mentioned objeets'I have rovided for eachplow body a bracket secured to the rear obliquelyset bar of the.triangular frame having two rearwardl extending sides or lugs parallelto the line ofy draft and two drag beams each having forwardly`extending bars ksecured to the same, and held to ivot upon the bracket,and one of said bars having a device forlorngitudinally adjusting thedrag beam to which it is attached, the whole being constructed andarranged as hereinafter Inore particularly explained.

Figure 1, is a plan view of a traction gang plow having the 'triangularframe or hitch and provided with my improvements. Fig. 2, is aperspective view of the triangular frame or hitch. Fig. 3, is asectional detail showing 'a preferred form of vertical journal for acaster wheel at the front of a bracket attached to the front bar of theframe. Fig. 4, is a sectional detail elevation passing through thecenter of one'of the lcross bolts connecting one set of plow drag beamsto the plow frame or hitch. Fig. 5, 1s a plan view of Fig. 4, partiallyin section. Fig. 6, is a detail of the eccentric washer.

In the drawings like letters of reference'indicate corresponding partsin each ligure.

A is a triangular frame or hitch comprising the front bar A which isdesigned to be 'drawn at right angles to the line of draft, an obliquerear bar A2 which is connected to the front bar by a corner angle plateAl and a side bar A, which is suitably bolted to the front and rear barsand substantially lies parallel to the line of draft. A5 is a reinforc-Ingbar suitably secured to the front and Irear bars. The frame isotherwise bracedas indicated. All the bars A A2 and A4 are angle bars.

y ',lhe leading wheels o r ruiming supports are preferably locatedforward of the triangular frame, so that the frame may be lower thanwould be possible if the wheels were under the frame, but it is ossibleby'raising the frame and lowering t e devices for bitching the frame tothe engine and hit'ehing the plow drag beams to the frame to allow'theforward leading wheels or running supports to run or turn under theframe.

I have illustrated in the drawings, and

now proceed to describe, though without the bars.

the bar A, and provided with end grooves B2 and B3 in which are held inparallel ar- D is a trunnion, which is preferably tapered at theto'p andextends through ac orrespondingly tapered hole -in the` bearing block C.'l'he lower portion of the trunnion D flares outward as indicated and isrovided with grooves D into which fit the ars D2 in the lower ends ofwhich carried a wheel D3.

D4iare bolts which extend throughto the Haring portion of the trunnionand bars D2.

E is a boltwhich passes up through the taered trunnion and through avflaring washer D@ which rests on top of the block C. A suitable nut Fis placer on the to i of the bolt to secure it in position and there ycomplete the bearing and caster wheel.

G are braces extending from the front bar A to the inner bars B1L andB5.

`IFI and H are hitching blocks, which are secured to the front bar A andconsist each of the bracket H', sleeve H2, held by a bolt in the bracketand the clevis H3. 'l` here is however no special feature about thehitching blocks. j

I and J are reverse U-shape plates bolted to theunder side of the frontbar A and the rear bar A2 respectively and having their sides projectingdownward and parallel to the line of draft. narrow side of thetriangular frame and near the-junction of the front bar A with the rearbar A2 substantially opposite to each other, and their sides or downwardprojections are res ectively in line with each other.

and K" are bars secured at the front and I intermediate of their lengthto the bars I and J respectively and extending'rearward,parallel to theline of draft far enough to permit j ournaled in the ends of the bar's Kand K in y rear of the bar A2.

M is a supporting Wheel located on the out- ;js'ide of and near the rearend of the side bar Af and in proximity to the rear apex of thetriangular frame or hitch, and has an axle INI held beneath the bar A2bythe U-bolt M2 and beneath the bar A4 by the bearing bracket M3. i

are brackets having oblique front ends which are bolted to the obliquerear bar A of the triangular frame. The rearwardly projecting sides ofthe bracketsare parallel They are situated on the to the line ofdraft'and are sufiicient-ly far apart to give a laterally rigid bearingfor the double plow drag beams. It will be understood that there -is onebracket N for each plow and set of drag beams.

O is a plowbody and O the two plow drag beams thereof, which haveattached to the front ofthe same the forked connecting bars C2 bythebolts O3.

Extending through the longitudinal slots C4 in one of the forked membersof the bar (see Figs. 4. and 5) are projections O5 extending from thebar O2 to the rear of the. slots O4. C6 are eccentric washers throughwhich and the slots O4 and the plow drag beam O thebolts O3 pass.` Thewashers O are provided with iat sided portions O7 designed'to abutagainst the projections O5. The washers O6 being eccentric to the boltsO34 the position of the drag beam may be adjusted longitudinallybetweenthe forks of the bar C by loosening the bolts O3 and turning thewashers so as 'to bring a different side of the 'washers against theprojection O5, thus alining each set of plow drag beams with the othersets and at right angles to the front of the frame or parallel t0 thevline of draft. In the case of each set of plow drag beams theconnecting bars C2 are provided in the forward portion of their sideswhich fit close .against the sides of the corresponding bracket withorifices and through these oriices, and orifices in the rear portion ofthe sides of the corresponding bracket N,a cross bolt P extends, thewhole servingto give a bearing laterally rigid for each set of vplowdrag beams and consequently for the plowbody and `yet al freely movingswinging or pivotal bearing for the raising or rising and falling of theplowbody.

By the leading wheels or running supports hereinbefore described, and bythe wheels L and M it will be seen that the plow frame or' hitch will beproperly supported, and yet it can be drawn readily and turned readily.It will be further 'seen that said wheel or running supports also serveto keep the frame or hitch of the plow substantially parallel with thesurface of the ground, which is an important feature as'the plow isthereby prevented from dipping too deeply into the solid, or

rising so much that it will not follow the undulations ofthe groundproperly.

The connection of each lowbody to the triangular frame or hitch liiymeans of the two plow drag beams connecting bars and brackets N is alsostrong and holds the plowbody rigid laterally while permitting of itsfree movement up and down notwithstanding the level position maintainedby the frame or hitch support as hereinbefore described.

What I claimA as my invention is:
